The defining feature of a prokaryotic cell is C. Membrane- bound organelles.
I hope this helps! :>
Explanation:
Avg speed × total times = total distance
20×25=500
Since acceleration in the 1st interval is same as deceleration in the 3rd interval and deceleration is from the same velocity achieved after acceleration, t

The answer is B) hope this helped you
Answer:
Explanation:
B) The pentose in the hairpin adopts only the C-3\' endo pucker conformation.
C) The hairpin adopts a right-handed helix with a diameter of 26 Å .
D) The hairpin contains G:C, A:U, and sometimes G:U base pairs.
DNA and RNA are both nucleic acids. Aside the structural difference of DNA being double stranded and RNA being single stranded, in DNA, the nucleotide bases adenine (A) is paired with thymine (T); while cytosine (C) is paired with guanine (G); howerver in RNA, thymine is replaced with uracil.; thus in RNA, the base pairs are - A:U and G:C
RNA however sometimes take on a dynamic structure, called the wobble case pair where guanine and uracil pair - G:U.
The diameter of RNA is 26 Å, while that of DNA is is 20 Å
The ribose in RNA with a helical structure has a C3’ endo conformation.
